jQuery基于serializeArray的serializeObject

//work with jQuery 1.x
jQuery.prototype.serializeObject=function(){
	var obj=new Object();
	$.each(this.serializeArray(),function(index,param){
		if(!(param.name in obj)){
			obj[param.name]=param.value;
		}
	});
	return obj;
};

<form>
	<input type="text" name="username" />
	<input type="text" name="password" />
</form>

jQuery("form").serialize(); //"username=&password="
jQuery("form").serializeArray(); //[{name:"username",value:""},{name:"password",value:""}]
jQuery("form").serializeObject(); //{username:"",password:""}

//work with jQuery 2.x
jQuery.prototype.serializeObject=function(){
	var hasOwnProperty=Object.prototype.hasOwnProperty;
	return this.serializeArray().reduce(function(data,pair){
		if(!hasOwnProperty.call(data,pair.name)){
			data[pair.name]=pair.value;
		}
		return data;
	},{});
};

//work with jQuery Compact 3.x
jQuery.prototype.serializeObject=function(){
	var a,o,h,i,e;
	a=this.serializeArray();
	o={};
	h=o.hasOwnProperty;
	for(i=0;i<a.length;i++){
		e=a[i];
		if(!h.call(o,e.name)){
			o[e.name]=e.value;
		}
	}
	return o;
};
